NEW BOOKS.

A Handbook of American Private Schools, 1919 Edition. By Porter E.

Sargent. Boston. Pp. 761. Price $3.00.

Each year this Handbook improves in completeness, usefulness and
authority. It is a book that no one having dealings with the private
schools or summer camps of this country can afford to be without. It
lists both schools and camps in easily accessible form, and gives their
characteristics in a fairminded, comprehensive way that cannot fail to
help parents as well as educators.

The discussion of formative movements, the bibliography, and other
such information is invaluable to the school itself.

Applied Science for Wood-Workers. By William H. Dooijey. New
York : The Ronald Press Co. Pp. viii + 457. Price $2.00.

Applied Science for Metal Workers. By the same author. Pp. viii + 479.
Price $2.00.

The same principle underlies these two books, that of giving a practical
understanding of general science, and building on that foundation the
technical science needed for the trade in question. The texts are iden-
tical through the first 368 pages, after which each one takes up the applied
science fitted to its title.

While these books are particularly well fitted for use in vocational or
trade schools, they seem to present interesting possibilities for use in a
general high-school course, for their practical handling of everyday prob-
lems, illustrated, as it is, with photographs and examples from many
industries, gives a very concrete and interesting approach to science.

Number by Development. Vol. II., Intermediate Grades, 486 + xi. Vol.
III., Grammar Grades, 514 + xx. By John C. Gray. Philadelphia:
J. B. Lippincott Co.

These books not only discuss the principles applicable to number teach-
ing, but give the details of the development of the important parts of
the subject so that they furnish the teacher with a plan for the class
development of new ideas and methods. Vol. II. takes up fractions,
while Vol. III. is largely concerned with decimals, measurement, and
the use of percentage and its applications.

The books are partly the result of experiment and trial in the schools
of Clearfield, Massachusetts, of which Mr. Gray is Superintendent

Junior High-School Mathematics, Third Course. By William L. Vos-
burgh and Frederick W. Gentleman. New York: The Macmillan
Company. Pp. viii + 295.
